RESUMEN

No official data exist on the status of musculoskeletal (MSK) radiology in Europe. The Committee for National Societies conducted an international survey to understand the status of training, subspecialization, and local practice among the European Society of Musculoskeletal Radiology (ESSR) partner societies. This article reports the results of that survey. An online questionnaire was distributed to all 26 European national associations that act as official partner societies of the ESSR. The 24 questions were subdivided into six sections: society structure, relationship with the national radiological society, subspecialization, present radiology practice, MSK interventional procedures, and MSK ultrasound. The findings of our study show a lack of standardized training and/or accreditation methods in the field of MSK radiology at a national level. The European diploma in musculoskeletal radiology is directed to partly overcome this problem; however, this certification is still underrecognized. Using certification methods, a more homogeneous European landscape could be created in the future with a view to subspecialist training. MSK ultrasound and MSK interventional procedures should be performed by a health professional with a solid knowledge of the relevant imaging modalities and sufficient training in MSK radiology. Recognition of MSK radiology as an official subspecialty would make the field more attractive for younger colleagues as well as attracting the brightest and best, an important key to further development of both clinical and academic radiology. KEY POINTS: · Standardized training and/or accreditation methods in the field of MSK radiology is lacking at a national level.. · With certification methods, such as the European diploma in musculoskeletal radiology, a more homogeneous European landscape could be created in the future with a view to subspecialist training.. · Recognition of MSK radiology as an official subspecialty would make the field more attractive for younger colleagues as well as attracting the brightest and best, an important key to further development of both clinical and academic radiology..

RESUMEN

Good outcomes following treatment of pelvic ring injuries, acetabular fractures, and femur fractures rely on restoration of native pelvic or limb alignment, anatomical reduction and rigid stability of articular fractures, and early postoperative mobilization. Multiple surgical approaches, reduction aids, and orthopaedic implants are available to stabilize these fractures. Despite best practices, complications including hardware failure, nonunions, malunions, and infections occur. This article discusses common fracture classification systems, implants, and imaging findings associated with unwanted complications in fractures of the pelvis, acetabulum, and femur.

RESUMEN

Related to fractures of and around the knee, inappropriate technical factors related to the surgery, severe comminution of the fracture, early overly arduous rehabilitation of the patient, and patient-related noncompliances may have the potential for the risk of inadequate fixation and other complications. Loss of fixation, malunion/nonunion, infection, arthritis, arthrofibrosis, and symptomatic hardware are among postsurgical complications that may necessitate further reconstructive techniques. In this review, complications that may be encountered in the postsurgical period of fractures involving the patella, supracondylar femur, and tibial plateau are described.

RESUMEN

Benign masses arising from facial bones have been reported several times in the literature. Hemangiomas are one of the uncommon benign tumors. In this study, the authors aimed to present a rare patient of zygomatic intraosseos hemangioma and their management. A 40-year-old woman with a mass in her left lateral cantus admitted to our clinic. Preoperative computed tomography and magnetic resonance imaging revealed an osseos mass in her left zygoma. The authors conclude that it should be kept in mind that although they are very rare benign tumors, intraosseos hemangiomas can cause facial masses. Meticulous radiologic examination can give important clues for differential diagnosis before the surgery.

RESUMEN

OBJECTIVE: To test contrast to noise ratios (CNRs) of both diffusion-weighted (DW) images and contrast enhanced images in terms of the visual assessment of activity in sacroiliitis of ankylosing spondylitis (AS) patients. MATERIALS AND METHODS: The study included 21 patients with AS. All patients were examined with STIR, FST1/Gd and DWI (b = 0,600). A total of 54 hyperintense lesions on STIR were noted in their sacroiliac joints divided into four quadrants. CNRs were calculated for all of the sequences above. A second group of patients (n = 7) with normal sacroiliac joints (SIJs) served as controls. A total of 56 CNR measurements from apparently normal subchondral bone marrow in this control group were done as well. The differences between scores were tested for significance (SPSS version 17.0) using Wilcoxon's test in which p values lower than 0.01 were considered statistically significant. RESULTS: In the first group with sacroiliitis, mean CNRs for STIR, FST1/Gd, DWI were 32.97, 30.16 and 24.47, respectively. Mean CNRs in the second group with normal SIJs were calculated as 3.52 , 2.99 and 3.96, respectively . There was a statistically significant difference between the CNR measurements of the first and the second group (p = 0.000). Hyperintense lesions on STIR were depicted as "active" in the first group. Except for four lesions that were not included into the study, all of these hyperintense lesions were enhanced after contrast media administration. All of the "active" lesions were observed on DWI as well, at b = 600. No statistically significant difference between CNRs of contrast enhanced images and DWI and of contrast enhanced images and fluid sensitive sequences were found in the first group with sacroiliitis (p > 0.01). CONCLUSION: The CNRs are highest on STIR, followed by contrast enhanced images and DWIs. In terms of DWI and contrast enhanced images, there is no statistically significant difference between these two. Hence, contrast enhanced imaging can be replaced by DWI for visual analysis of active sacroiliitis, which is easy to apply without adverse affects of contrast media.

RESUMEN

OBJECTIVE: The aim of this study was to investigate the correlation of fibrosis stages in cases of chronic hepatitis by comparing shear wave elastography and diffusion-weighted magnetic resonance imaging. METHODS: A total of 46 chronic hepatitis patients with an age range of 20-50 years were classified into three groups based on their fibrosis stages. Comparison group 1: the presence of fibrosis (S0 and S1≤); comparison group 2: the presence of significant fibrosis (≤S2 and S3≤); and comparison group 3: the presence of cirrhosis (≤S4 and S6). Shear wave velocities were measured by acoustic radiation force impulse elastography. Diffusion-weighted magnetic resonance imaging was performed on a 3.0 Tesla MRI device. RESULTS: In comparison group 1 (S0 and S1≤), the area under the curve, sensitivity, and specificity of acoustic radiation force impulse values were 0.784, 87, and 60%, respectively, while these values were 0.718, 80, and 66%, respectively, for apparent diffusion coefficient . In comparison group 2 (≤S2 and S3≤), the area under the curve, sensitivity, and specificity of acoustic radiation force impulse values were 0.917, 80, and 86%, respectively, and the apparent diffusion coefficient values were 0.778, 90, and 66%, respectively. In comparison group 3, the area under the curve, sensitivity, and specificity of acoustic radiation force impulse values were 0.977, 100, and 95%, respectively. There was no statistically significant difference between the apparent diffusion coefficient values of the cases in the three groups (p=0.132). CONCLUSION: Noninvasive methods are gaining importance day by day for staging hepatic fibrosis. Acoustic radiation force impulse elastography was evaluated as a more reliable examination than diffusion-weighted magnetic resonance imaging in revealing the presence of fibrosis, determining significant fibrosis, and diagnosing cirrhosis.

RESUMEN

Psoriatic onycho-pachydermo-osteo/periostitis (POPP) syndrome is a rare form of psoriatic arthritis with a combination of (i) psoriatic onychodystrophy, (ii) connective tissue thickening, and (iii) periostitis of the distal phalanges. The treatment of the condition has generally been reported to be unsatisfactory with the traditional regimes. Here, we describe a case whom we believe is one presentation of POPP with extensive bone marrow edema of metacarpal bones without distinctive periostitis.

RESUMEN

The oto-spondylo-mega-epiphyseal-dysplasia (OSMED) phenotype is an autosomal recessive trait that is a skeletal dysplasia with the hallmark findings of limb shortening, multiple skeletal and radiological abnormalities, mid-face hypoplasia with a flat nasal bridge, small upturned nasal tip, and sensorineural hearing loss. A 3.5-year-old girl born to consanguineous Turkish parents had characteristic facial features at birth: mid-face hypoplasia, mild hypertelorism, upslanting palpebral fissures, prominent supraorbital ridges, depressed nasal bridge, small upturned nasal tip, long philtrum, and micrognathia. Radiological examination at three years of age revealed large flaring metaphyses and wide flat epiphyses. The humerus and femur showed the characteristic dumbbell shape. She had bilateral hearing loss with no ophthalmologic findings. There is continuing debate over the clinical overlap and differential diagnosis of OSMED syndrome. The patient was examined considering Weissenbacher-Zweymuller, Stickler type 3, Marshall syndrome, and Kniest dysplasia as possible differential diagnoses. We believe that the presented patient clinically manifested features of OSMED syndrome. We would like to point out that the management of OSMED calls for a coordinated multidisciplinary approach.

RESUMEN

Ionizing radiation is known to induce mutations and cell transformations, predominantly by causing single-strand and double-strand DNA breakage, thereby leading to chromosome instability and carcinogenesis. The aim of this study was to evaluate genotoxic effects in hospital staff exposed to low-dose ionizing radiation in comparison with a selected control group, by using the cytokinesis-blocked micronucleus (CBMN) and sister chromatid exchange (SCE) tests in peripheral blood lymphocytes. The study included 40 exposed radiology staff and 30 control subjects. The frequency of micronuclei (MN) was significantly increased in radiation-exposed groups compared with control persons (p < 0.05). The frequency of SCE did not show any significant difference in the exposed individuals in comparison to the controls. Our results showed that low-level chronic occupational exposure to ionizing radiation causes an increase of MN frequency in chromosomes, even though the absorbed doses were below the permissible limits. Our studies indicate that the CBMN assay is considered to be sensitive test in contrast to SCE analysis to evaluate chromosomal damage induced by ionizing radiation.

RESUMEN

OBJECTIVE: As part of the lateral ligament complex of the elbow, the annular ligament has an adjunctive role in stabilizing the proximal radioulnar joint. Knowledge of the anatomy of this ligament may enhance our understanding of its functional role in maintaining integrity of the elbow joint in fracture and dislocation. The purpose of this study is to provide a detailed analysis of the anatomy of the annular ligament using MR arthrography with anatomic and histologic correlation in cadavers. MATERIALS AND METHODS: MR arthrography of six fresh cadaveric elbows using coronal, axial, and sagittal planes was performed after injection of intraarticular contrast material. The MR arthrography appearance of the annular ligament was correlated with anatomic sectioning and histologic analysis. RESULTS: On MR arthrography, the axial and sagittal planes provided the best evaluation of the annular ligament. Although the anterior attachment of annular ligament was a single band, the posterior attachment was fenestrated in two of six specimens. Anatomic inspection confirmed the MR observations. On histology, the annular ligament appeared to be part of a complex supporting structure continuous with the elbow joint capsule, adjacent ligaments, and muscles. CONCLUSION: The annular ligament is a complex structure formed from the capsule, lateral collateral ligamentous complex, and supinator muscle that act in unison to stabilize the proximal radioulnar joint. Its posterior attachment to the ulna can be fenestrated normally. A detailed analysis of anatomy of this ligament allows us to better understand its functional role in fractures and dislocations of the elbow joint.

RESUMEN

OBJECTIVE: The purpose of this study was to use MRI and anatomic correlation in cadavers to delineate the anatomic features of the distal attachment of the brachialis muscle. MATERIALS AND METHODS: MRI was performed on 13 cadaveric elbows. The MRI findings were compared with those in anatomic sections and histologic preparations. The brachialis muscle of one cadaver was dissected. RESULTS: The dissected brachialis muscle had two heads, superficial and deep. The attachment of the superficial head to the ulnar tuberosity was farther distal than that of the deep head. The attachments of all aspects of the muscle included a tendinous layer rather than purely muscular structures. Histologic analysis showed no direct communication between the brachialis and biceps brachii tendons or between the brachialis tendon and joint capsule. CONCLUSION: Familiarity with the anatomic features of the distal brachialis muscle and tendon is essential for accurate assessment of these structures.

RESUMEN

INTRODUCTION: The purpose of this study was to assess the flap reconstructed hind feet of patients with MRI who were traumatized by land-mine. MATERIALS AND METHODS: T1 and T2 weighted images were obtained in 7 patients, 12 months later the reconstruction of their hind feet by myocutaneous flaps after land-mine trauma. RESULTS: In all patients T2 signal intensities of the myocutaneous flaps were slightly high compared to normal undisturbed muscle. Slight vascular engorgement was noted in the vicinity of the flaps in all cases. There were ankle joint ankylose (n=1), tarsal coalition (n=3), sklerosis within the calcaneus (n=1), bone cortex irregularities (n=3), absence of calcaneus (n=4), deformity in talus and bone marrow edema (n=1), navicular edema (n=2), remodeling in the superior aspect of talus neck (n=2), absence of talus (n=2), talocalcaneal ankylose (n=1), small collection in the superior aspect of flap (n=1), drenage canules (n=1). CONCLUSION: In reconstructed hind feet by myocutaneus flaps done for land-mine traumas, MRI presents useful information by displaying detailed anatomy of the flaps, bones, joints, soft tissues and associated complications.

RESUMEN

Pelvic masses, especially hydatid disease, rarely present with sciatica (1, 2). We present the computed tomography (CT) and the magnetic resonance imaging (MRI) findings of a 49-year-old female patient with presacral hydatid disease, who was evaluated for her sciatica. We also want to emphasize the importance of assessing the pelvis of patients with symptoms and clinical findings that are inconsistent and that cannot be satisfactorily explained by the spinal imaging findings.
